Systems, articles, and methods for electromyography sensors
First Claim
1. A method of fabricating an electromyography (“
- EMG”
) sensor, the method comprising;
forming a first sensor electrode on a first surface of a substrate, wherein forming a first sensor electrode on a first surface of a substrate includes depositing at least a first layer of a first electrically conductive material on the first surface of the substrate;
depositing an amplifier on a second surface of the substrate, the second surface opposite the first surface across a thickness of the substrate;
depositing a first capacitor on the second surface of the substrate;
depositing a first resistor on the second surface of the substrate; and
forming a first electrically conductive pathway that communicatively couples the first sensor electrode and the amplifier through the first capacitor and the first resistor.

Abstract
Systems, articles, and methods for surface electromyography (“EMG”) sensors that combine elements from traditional capacitive and resistive EMG sensors are described. For example, capacitive EMG sensors that are adapted to resistively couple to a user'"'"'s skin are described. Resistive coupling between a sensor electrode and the user'"'"'s skin is galvanically isolated from the sensor circuitry by a discrete component capacitor included downstream from the sensor electrode. The combination of a resistively coupled electrode and a discrete component capacitor provides the respective benefits of traditional resistive and capacitive (respectively) EMG sensor designs while mitigating respective drawbacks of each approach. A wearable EMG device that provides a component of a human-electronics interface and incorporates such capacitive EMG sensors is also described.
